WITHDRAWN IEC 61914:2015 | Cable Cleats For Electrical Installations
May 11th, 2022
This article is intended to highlight IEC standard and specification updates in relation to short-circuit testing and purchasing of cable cleats.
The previous 2nd Edition of IEC 61914:2015 has now been withdrawn and replaced with IEC 61914:2021 – the 3rd Edition of the standard. This edition constitutes a technical revision of which we will detail below.
All cable cleats distributed by Thorne & Derrick are currently undergoing testing procedures to conform to the latest IEC 61914:2021 standards.
Certification will be in place before the deadline.
So What’s Changed?
IEC 61914:2015 Is Withdrawn
The new standard is available as IEC 61914:2021 CMV which contains the International Standard and its commented version, providing a quick and easy way to compare all of the changes between IEC 61914:2021 edition 3.0 and the previous IEC 61914:2015 edition 2.0.
View the document here.
IEC 61914:2021 specifies requirements and tests for cable cleats and intermediate restraints used for securing cable in electrical installations. Cable cleats provide resistance to electromechanical forces where declared. This document includes cable cleats that rely on a mounting surface specified by the manufacturer for axial and/or lateral retention of cables.
This third edition cancels and replaces the second edition published in 2015. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
a) Requirements for mandrels used in testing rationalised and detailed in the general test requirements (Clause 5);
b) Definition of liner added and test requirements where liners and other optional parts are used;
c) Definitions for LV, MV and HV cables added and test requirements where MV & HV cable are used ;
d) New corrosion resistance classes for plated products added;
e) New requirements and test for durability and legibility of markings added;
f) New test requirements for axial load testing of cleats for more than one cable added;
g) Lateral load test requirements for intermediate restraints added
“Cable cleats are critical electrical safety products – in the event of a short circuit they can protect your people, not just plant. During a recent tender bid we were alerted to non-conformance of a competitor product during the technical qualification procedure for a major UK infrastructure project. Simply, their product was tested to the cancelled 2009, not superseding 2015 version. Thorne & Derrick distribute LV HV Cable Accessories & Electrical Equipment from market-leading manufacturers tested to the current range of international standards,” comments Chris Dodds (Sales Manager at Thorne & Derrick).
“The closest example I can think of for this is car seat belts. If you were on the market to purchase a car and were advised that the seatbelts on the car you had chosen were not compliant to the latest industry standards, you may decide against purchasing that car due to safety concerns. Moreover the car would not be safe for sale in UK or European markets and would not bear the required UK CA or CE mark. Cable cleats for cables can be viewed in a similar way to seatbelts in cars as they both perform safety functions, adds Noman Shabir (National Sales Manager at Ellis Patents).
All cable cleats stocked and supplied by Thorne & Derrick are short-circuit tested to the current updated version IEC61914:2015, and are undergoing testing to achieve IEC61914:2021.

Cable Cleats | Importance, How To Specify & International Standards
May 9th, 2022
What Are Cable Cleats?
“A cable cleat is a device designed to secure electrical cables when installed at intervals along the length of the cables” – IEC 61914 Cable Cleats for Electrical Installations
“Cable cleats should:
Prevent excessive cable movement due to fault-current magnetic forces
Be rated for specific cable size and available current.”
The fifth edition of API Recommended Practice 14F (Design, Installation and Maintenance of Electrical Systems for Fixed and Floating Offshore Petroleum Facilities).
“Single core electric cables are to be firmly fixed, using supports of strength adequate to withstand forces corresponding to the values of the peak prospective short-circuit current.” – Lloyds Register. Rules and Regulations for the Classification of Ships, Part 6, Control, Electrical, Refrigeration and Fire.
“Cables are to be installed and supported in ways to avoid chafing and undue stress in the cable.” – ABS Steel Vessel Rules 4-8-4/21.9 Cable Support, 4-8-4/21.9.1 General and 4-8-4/21.9.3 Clips, Cable Saddles, Straps
“In order to guard against the effects of electro dynamic forces developing on the occurrence of a short-circuit or earth fault, single core cables shall be firmly fixed, using supports of strength adequate to withstand the dynamic forces corresponding to the prospective fault current at that point of the installation.” DNV Rules for Ships / High Speed Light Craft and Naval Surface Craft, Pt. 4 Ch. 8 Sec.10 – page 68, C50
ALWAYS REMEMBER: Any power cable system designer or installer has an obligation to consider the method of securing cables in order to restrain their movement whether caused by an electrical fault or any other reason – a job that can only be safely and securely done with correctly specified cable cleats.
HOW TO SPECIFY A CABLE CLEAT?
- Calculate the system peak fault current
- Identify the specification of the cable to be used including the nominal cable diameter and the manufacturing tolerance
- Identify the support structure type e.g. Ladder ( including rung spacing), basket, individual steel structure etc
- Consider support structure material type e.g. stainless steel, galvanised steel etc
- Consider the environmental conditions
- Consult with Ellis Patents who will provide you with the most cost effective solution for your needs
WHAT IS THE INTERNATIONAL STANDARD FOR CABLE CLEATS?
IEC 61914 Cable cleats for electrical installations outlines a series of tests that can be used to assess the performance of a cable cleat’s design.
Although the standard does not define pass or fail levels, it allows manufacturers to define the performance characteristics of their products, and specifiers to compare products from different manufacturers.
The aspects of construction and performance covered by the standard include:
- Material type – i.e. metallic, non-metallic or composite
- Minimum and maximum declared service temperatures
- Resistance to impact at the minimum declared operating temperature
- The ability of the cable cleat to withstand axial slippage forces
- Resistance to electro-mechanical forces – i.e. the ability of the cable cleat to withstand the forces between the cables in the event of a short-circuit
- Resistance to UV and corrosion
- Flame propagation
TRANSPORT FOR LONDON PROJECT
Working with Ellis Patents we completed the specification and have now moved into manufacturing for our largest contract to date to supply TfL (London Underground) approved cable hangers across several depot modernisation projects.
Thorne & Derrick in consultation with the Asset Manager at Transport for London and their appointed Telecoms & Power contractor secured formal Authorisation & Approval for the Pegasus range of non-metallic cable support hangers. The product will provide safe cable management of the cable route within the Bridges & Structures category – over 1000 hangers with proven lifecycle performance and utilising the standard J-type design for support of multiple cable runs including single, 3-way and 5-way configurations are now scheduled for delivery.

Stokbord® Drum Cable Protection Installation For Dogger Bank Wind Farm (A & B)
May 9th, 2022
Stokbord® Drum Cable Protection
Stokbord® Drum has shown its strength once again on one of the world’s largest renewable energy projects – Dogger Bank Wind Farm. Funded by SSE Renewables, Equinor and ENI, Dogger Bank Wind Farm will be the largest wind farm in the world, and once complete it will be capable of powering over 6 million homes in Britain.
As always, great infrastructure needs great protection. Centriforce are proud to share that Stokbord® Drum has been installed as part of the cable protection system for Dogger Bank Wind Farm (A & B).
Stokbord® Drum delivers heavy-duty utility protection in a single material strip, allowing operatives to install cable protection directly into the trench without needing to set foot into it. Centriforce wind their protection material directly onto an industrial reel which allows users to unroll the material into application, providing significant health and safety benefits alongside major time and cost savings.
Stokbord® Drum has been developed to provide a mechanical installation option decreasing the need for any manual work
➡ Centriforce, working through their distributor network including Thorne & Derrick stock and supply Stokbord cable covers and Tapetile cable warning tapes that offer clear visual warning and excellent cable impact protection for 11kV-33kV high voltage cables including EHV circuits operating at 66kV, 132kV up to 400kV.
Cable Protection Installation
These specifications make Stokbord® Drum the perfect partner for large scale projects as heavy-duty cable protection can be installed in a matter of minutes without the need for individual peg connection as required by traditional protection tiles.
Centriforce met with Jones Bros Civil Engineering on the East Riding Cable Route for Dogger Bank Wind Farm (A & B) to see how Stokbord® Drum supported their team on this project.
Commenting on the speed of installation, James Lockwood – Project Manager for Jones Bros Civil Engineering says “It is estimated we can install 250 metres of Stokbord® Drum within 3 minutes, using 2 men. In comparison, it could take up to 90 minutes using 4 operatives and traditional plastic covers.”
On this project, Stokbord® Drum has allowed operatives to install cable protection up to 30x faster than traditional methods. This is an incredible advantage for contractors. With fewer operatives required to work on a single 250m stretch of cable, Stokbord® Drum saves time and costs by allowing more operatives to cover greater distances in a shorter space of time.
Key Benefits of Stokbord® Drum:
- Ease and speed of installation – up to 30x faster to install than traditional plastic covers
- Significant reduction in manual handling costs
